DSP5509的RTC实验-第3篇
1. RTC实时时钟，不在过多介绍，本例程直接调用芯片支持库CSL的库函数，用起来比较简单
1 main() 2 { 3 CSL_init(); 4 printf ("\nTESTING...\n"); 5 6 RTC_reset(); // Reset the registers 7 RTC_config(&myConfig); // Initialization 8 RTC_getConfig(&Config); 9 printf ("RTCSEC value is: %x\n",Config.rtcsec); 10 printf ("RTCMIN value is: %x\n",Config.rtcmin); 11 printf ("RTCHOUR value is: %x\n",Config.rtchour); 12 printf ("RTCDAYW value is: %x\n",Config.rtcdayw); 13 printf ("RTCDAYM value is: %x\n",Config.rtcdaym); 14 printf ("RTCYEAR value is: %x\n",Config.rtcyear); 15 16 RTC_setTime(&myTime); 17 RTC_getTime(&getTime); 18 printf("Current RTC time is: %x:%x:%x\n",getTime.hour,getTime.minute,getTime.second); 19 20 RTC_getDate(&getDate); 21 printf("Current RTC date is: %x/%x/%x\tDay of week: %x\n",getDate.month,getDate.daym,getDate.year,getDate.dayw); 22 23 /* Set an alarm at the time specified by myAlarm */ 24 /* Alarm needs to be enabled to occur */ 25 RTC_setAlarm(&myAlarm); 26 printf("Alarm time: %x : %x : %x\tDay of week: %x\n", 27 RTC_FGET(RTCHOURA,HAR),RTC_FGET(RTCMINA,MAR), 28 RTC_FGET(RTCSECA,SAR),RTC_FGET(RTCDAYW,DAR)); 29 30 RTC_start(); // start the RTC running 31 }
2. 感觉和STM32的RTC差不多，比较简单，在本例程中有2个疑问，TMS320C5509和TMS320C5509A有和区别？printf函数打印是什么机制？实际运行的时候，发现程序卡在如下函数，怀疑是标准C库的底层没支持这个函数。
1 printf ("RTCSEC value is: %x\n",Config.rtcsec);
3. 实际测试发现printf可以打印在CCS的console窗口，调试很方便。
